Stop 4: Drive along the N. flank road through the lahar field, of which the 1877 lahar deposits are so evident. Drive along the Water canal road to the bend, then walk S for 1 km, viewing the scenery, seeing and sampling the 200 ky Chalupas pyroclastic flow deposits, and seeing the N. flank drainage network on map to understand the threats to downstream communities and infrastructure.
